Hi AsiyaKhanom,

If your package from the UK is still stuck in customs in Shenzhen, there could be several reasons for the delay. Here are the most common causes and what you can do:

Possible Reasons for the Delay:
Customs Inspection

Packages are sometimes randomly selected for inspection, especially if they contain high-value items, restricted goods, or incomplete documentation.

If customs suspects undervaluation or incorrect declaration, they may hold it for verification.

Missing or Incomplete Documentation

If the sender did not provide a proper commercial invoice, customs declaration, or other required paperwork, clearance may be delayed.

For gifts or personal items, incorrect labeling (e.g., wrong HS code) can cause hold-ups.

Taxes or Duties Owed

If your package exceeds China's tax-free threshold (CNY 50 for most items), customs may hold it until duties/VAT are paid.

You might receive a notification from the courier (e.g., DHL, FedEx, EMS) to pay fees before release.

High Volume of Shipments

Shenzhen is a major international logistics hub, so customs may experience backlogs, especially during peak seasons (e.g., holidays, sales events).

Restricted or Prohibited Items

Certain goods (e.g., electronics, cosmetics, branded goods, supplements) may require additional permits or face restrictions.

If your package contains such items, customs may detain it for further checks.

Security or Compliance Issues

If the package has suspicious contents (e.g., batteries, liquids), it may undergo extra screening.

What You Can Do:
Track Your Package
Use the tracking number to track.
If it says "Customs retention" (海关暂扣), it’s under inspection.

Contact the Courier or Customs

Call the courier’s China customer service (e.g., DHL China: +86 400 810 8000).

For EMS/China Post, call 11183 or check via WeChat (EMS-CN).

If duties are owed, the courier will usually notify the sender.

Submit Documents if Required
You might need to provide:

ID copy (护照/身份证)

Proof of payment (for tax assessment)

You need to contact the receiver in China to help you check if you couldn't do that.
